+Kernel Driver IBMPOWERNV
+========================
+
+Supported systems:
+
+  * Any recent IBM P servers based on POWERNV platform
+
+Author: Neelesh Gupta
+
+Description
+-----------
+
+This driver implements reading the platform sensors data like temperature/fan/
+voltage/power for 'POWERNV' platform.
+
+The driver uses the platform device infrastructure. It probes the device tree
+for sensor devices during the __init phase and registers them with the 'hwmon'.
+'hwmon' populates the 'sysfs' tree having attribute files, each for a given
+sensor type and its attribute data.
+
+All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in
+the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id'
+which the driver uses to make an OPAL call to the firmware.
+
+Usage notes
+-----------
+The driver is built statically with the kernel by enabling the config
+CONFIG_SENSORS_IBMPOWERNV. It can also be built as module 'ibmpowernv'.

+Sysfs attributes
+----------------
+
+======================= =======================================================
+fanX_input		Measured RPM value.
+fanX_min		Threshold RPM for alert generation.
+fanX_fault		- 0: No fail condition
+			- 1: Failing fan
+
+tempX_input		Measured ambient temperature.
+tempX_max		Threshold ambient temperature for alert generation.
+tempX_highest		Historical maximum temperature
+tempX_lowest		Historical minimum temperature
+tempX_enable		Enable/disable all temperature sensors belonging to the
+			sub-group. In POWER9, this attribute corresponds to
+			each OCC. Using this attribute each OCC can be asked to
+			disable/enable all of its temperature sensors.
+
+			- 1: Enable

+
+inX_input		Measured power supply voltage (millivolt)
+inX_fault		- 0: No fail condition.
+			- 1: Failing power supply.
+inX_highest		Historical maximum voltage
+inX_lowest		Historical minimum voltage
+inX_enable		Enable/disable all voltage sensors belonging to the
+			sub-group. In POWER9, this attribute corresponds to
+			each OCC. Using this attribute each OCC can be asked to
+			disable/enable all of its voltage sensors.
